How many radio stations can say a musical genre was born on its airwaves? On a Saturday night in December 1945, bluegrass music as we know it today began when a twenty-one-year old young man by the name of Earl Scruggs stepped up to the WSM microphone on the Ryman Auditorium stage to play the five-string banjo with a three-finger roll as part of Bill Monroe’s band. This was the final ingredient in a sound that also included guitarist/lead singer Lester Flatt, fiddler Chubby Wise, and bass player Cedric Rainwater, and of course the Father of Bluegrass, Monroe, himself. Listeners can still hear the sounds of Monroe and his Blue Grass Boys on 650 AM WSM.
